Explain what is meant by distributing test tasks for their simultaneous execution.

Distribution of test tasks for their simultaneous execution is the process of dividing the total set of tests into several parts that can be executed in parallel by different testers or automated systems. This allows for speeding up the testing process and increasing efficiency.

For example, if there are 100 tests, they can be divided into 4 groups of 25 tests each and run simultaneously on 4 different machines or threads. As a result, the total testing time is reduced by approximately 4 times.

Such distribution requires:

• Clear separation of tests without overlaps
• Synchronization of results
• Management of dependencies between tests (if any)

This is especially important in automated testing and when using CI/CD.
